I can no longer display the pdf files since version 2.18.1

Hello,

Since version 2.18.1, I can no longer display the pdf files on my club’s website: see https://www.cyclosyennois.fr/category/guidolyenne/
I’ve tested successively with all PDF.js updates up to version 2.2.1 and the problem persists. I was able to reinstall version 2.18 and the pdf display works correctly.
Do you have any idea what’s wrong?
the site
Version wp 6.6.1

Thanks for your help
